# Download the connector, Buff Code and the app > The connector for your network (git without handing over tokens), Buff Code on your organisation’s models, the Buff app for iPhone and Android. Cosign-signed. Connector · downloads · v0.22.5 # Download the connector The connector is a small self-contained agent you run **in your own network**. It connects your git server to the Buff platform — including when git is unreachable from the internet — **without giving us access tokens**. Integrations with trackers and knowledge sources are installed into it too. [Choose a build](https://buff.systems/en/downloads#binaries) [What it is and why](https://buff.systems/en/docs/connector) [Buff Code for developers](https://buff.systems/en/downloads#buff-code) Why you need it ## Your git connected — without direct access and without your tokens More in the connector documentation. Here are the essentials. ### Git behind a firewall GitLab / GitHub Enterprise / Gitea / Bitbucket Server in the internal network — the connector reaches it from inside and carries repositories to us and back. ### Tokens stay with you Even for cloud git you need not give us access tokens: they are stored in the agent, in your network, and never reach us. ### Outbound only The agent only calls out to the Buff relay — nothing connects into your network, except in two cases that arrive only by webhook: GitLab commit comments, and Figma when its connection lists neither files nor projects. It touches git only for a task. Binaries ## Choose your OS and architecture A single self-contained executable. Install it on any machine in your network with access to the git server and outbound internet access. The binary needs git installed; integrations need Linux, root (or CAP\_SETUID) and Python 3.11+, because each one runs as a separate process under its own OS user. ### Linux - [amd64 connector-linux-amd64](https://buff.systems/downloads/v0.22.5/connector-linux-amd64) - [arm64 connector-linux-arm64](https://buff.systems/downloads/v0.22.5/connector-linux-arm64) ### macOS - [Apple Silicon connector-darwin-arm64](https://buff.systems/downloads/v0.22.5/connector-darwin-arm64) - [Intel connector-darwin-amd64](https://buff.systems/downloads/v0.22.5/connector-darwin-amd64) ### Windows - [amd64 connector-windows-amd64.exe](https://buff.systems/downloads/v0.22.5/connector-windows-amd64.exe) - [arm64 connector-windows-arm64.exe](https://buff.systems/downloads/v0.22.5/connector-windows-arm64.exe) [SHA256SUMS](https://buff.systems/downloads/v0.22.5/SHA256SUMS) [cosign.pub (verification key)](https://buff.systems/downloads/cosign.pub) Authenticity check ## Check the checksum and the signature before running All artefacts come with checksums and are signed with cosign. Each binary has its .sig file next to it. ``` # 1.

Buff Code · 2.0.11-buff.36 ## An agent in your project folder — under your control An app and a console on your organisation’s models, knowledge and tools: every edit is visible, large tasks follow a plan, checks run on a schedule. It signs in through the company connector; there is no separate plan. ### Console Linux, macOS and Windows (Git Bash) — with one command. The script picks the build and verifies the checksum itself. ``` curl -fsSL https://buff.systems/install | bash ``` ### App - [Linux · AppImage buff-code-desktop-linux-x86\_64.AppImage](https://buff.systems/downloads/latest/buff-code-desktop-linux-x86_64.AppImage) - [Linux · deb buff-code-desktop-linux-amd64.deb](https://buff.systems/downloads/latest/buff-code-desktop-linux-amd64.deb) - [Linux · rpm buff-code-desktop-linux-x86\_64.rpm](https://buff.systems/downloads/latest/buff-code-desktop-linux-x86_64.rpm) - [macOS · Apple Silicon buff-code-desktop-mac-arm64.zip](https://buff.systems/downloads/latest/buff-code-desktop-mac-arm64.zip) - [macOS · Intel buff-code-desktop-mac-x64.zip](https://buff.systems/downloads/latest/buff-code-desktop-mac-x64.zip) - [Windows · x64 buff-code-desktop-win-x64.exe](https://buff.systems/downloads/latest/buff-code-desktop-win-x64.exe) [SHA256SUMS](https://buff.systems/downloads/latest/SHA256SUMS) [How to install and sign in](https://buff.systems/en/docs/buff-code) Mobile app ## Decisions don’t wait for the computer Buff for iPhone and Android: approve a task, answer the agent, allow a command in Buff Code, ask about documents — with notifications and end-to-end encryption.
